Arrange the following compounds in order of increasing Rf values in TLC Anthracene benzil tryphenylmethanol?
The order of increasing RF values in TLC is Benzil, methanol anthracene and tryphenyl.
What are the Rf values of amino acids?
The Rf values are very important in the analysis of amino acids in this situation. This is because they provide the information and basic groundwork data that can be used in reviewing the results of any further experiments.
Why is that the centre of the spot is considered when calculating Rf values for TLC?
outside are jus impurities
Why do you need to use a standard when performing electrophoresis?
To compare the atomic mass and rf values with the standard
What are the variables in a plan and design paper chromatography lab?
responding variable-distance of components( Rf values)
How are Rf values used?
Rf value to compare the "unknown" components of colored candy dyes with the "known" components of food coloring dyes.
How are values used?
Rf value to compare the "unknown" components of colored candy dyes with the "known" components of food coloring dyes.
Why are Rf values used?
Rf values are used mainly for simplicity. These values are generally easier to use to obtain percentages between a couple objects instead of using values that are already established.
Why Ni positive 2 and iron positive 3 ions have different Rf values?
Rf values are determined by the polarity of the substance tested. Even though these atoms may have similar electron configuration, it is not identical, and neither are their Rf values.
How are Rf values used in real life?
Rf values can be used to identify the type of drugs that had been taken by those who went through drug overdose.
How would you expect Rf values to change if you went from hexane-ethyl acetate solvent system to ethyl acetate only?
the rf values would increase
What are the significance of values?
Rf Values determine the solubility of a substance with respect to a certain solvent.

The order of increasing RF values in TLC is Benzil, methanol anthracene and tryphenyl.

How do fabric dyes work?
it stains the fabric the dyes color
If two samples have identical Rf values does this mean that they are necessarily identical molecules Explain?
No. The molecules MAY (and probably are if you are presented with this situation in school/college lab courses) be identical but just the Rf values is not enough information to determine, you must conduct additional tests. Two different molecules can have the same Rf value.Compound A will always have an Rf of X in solvent M. Compound B will always have and Rf of Y in solvent M. But, Rf X can be equivalent to Rf Y without compounds A and B being identical.
What is the risk-free rate if the expected return is 20.4 and beta is 1.6 and expected market return is 15?
expected market return = risk free + beta*(market return - risk free) So by putting in values: 20.4 = rf+ 1.6(15-rf) expected market return = risk free + beta*(market return - risk free) So by putting in values: 20.4 = rf+ 1.6(15-rf) where rf = risk free 20.4 - 24 = rf - 1.6rf -3.6 = -0.6rf rf = 6
